Solar panels and battery - any real world reccomendations?

I didn't like givenergy stuff either, their 5.2kwh battery is rubbish in the cold weather, (think 50-60% capacity) and the AC inverter is slow.
 
MyEnergy Solutions have said they can add 4 more panels with optimisers to my existing array, another battery and swap the inverter for an 8kw version.
They have quoted £7970 with bird netting.

Not sure I'll go for it as it seems a bit steep.

They wanted over £2000 just for an extra battery.

I'd still need to have a few vent tiles on the roof replacing with lower profile ones too if I want to have more panels.

[EDIT] I've contacted Spectra as well, to see what their prices are like.

It is 20% VAT included for £1450 aswell for your extra battery? As adding a battery to a system already in place is not exempt from the VAT like a full install is.
 
@Ace Modder might be if you got the system from spectra, they can cook the books and say that the battery was installed at a later date due to unforeseen circumstances/lack of components etc and hence saving the vat as it would then be tacked on to the original invoice...

@Ace Modder oh wait. No, its definitely vat-free without book-cooking. See @200sols link

This means the following will also now be included:

Standalone battery storage. - Projects in which a battery is fitted without supporting solar.
Retrofit batteries. - Projects in which a battery is retrofitted to an existing solar array.

We have a 5.2kwh givenergy and will probably double up at some point but I am going to leave it a few years so they hopefully get cheaper plus I dont want to use the same firm that did our installation, I might even try to DIY it.

The battery was at 100% by about 11am today, ok, its clouded over now so wouldnt have charged a significant amount today, but had it been sunny all day we would have easily charged 10 kwh, which given our use cooking dinner in the evening would cover us until the morning, then you can look at cheap night rates etc
 
@BUDFORCE that's exactly what I plan to do. Get a second battery (so 9.2kwh total) and swap to an eco7 tariff, charge the batteries overnight and during daylight hours can use solar and battery power, and selling on the excess solar for profit.
 
Thats what I've asked for a 10kWh battery setup with 8-10 panels, depending how many they can fit on our roof.
We have an EV car and a cheap 00:30am till 04:30am at 9p a kWh rate, day rate is 28p ish.

So the plan is to charge the car using mains at night during the 9p time from mains (and top up the batteries), hopefully the solar & batteries will provide power during the day and some excess may go into the battery, but I expect most of the battery juice will be from mains at night. I guess all this can be setup and controlled by the apps?

My daily use (excluding the night rate use) is around 16-17 kWh per day roughly as an average.

We ended up with Growatt in our system given the options we had. We were apprehensive about it at the time given some of the comments we'd heard, but having used it for a while now I'd probably take it again in preference to other options. It's not been long enough to talk about long term reliability yet, but the performance is good and exactly as claimed. We've also been happy to see the battery management logic is pretty reasonable too, which is not a given compared to what I've read about some BMS systems!

It's mostly a shame manufacturers won't tell you what they're doing (no charge/discharge curves VS temp, etc) before you buy and see for yourself though.
 
Got my quote now.
Seems a fairly decent quote with a 9.6kWh battery capacity.
Due to my needs a 3.5kW inverter is probs not quote enough for what I need (so Spectra said, this was after I explained that I have the usual usage of all background stuff plus a PC whioch is on from 8am till 10pm most days and the juice draw is typically 350-450w for much of that every day)

@Ace Modder that seems a bit more pricey than i'd have expected?
might be because they're using different components?
wonder how the quote will look like if they supplied the sunsynk ecco 5kw inverter and 2x sunsynk L5.1, rather than the lux/hanchu combo?

it'll still be slightly more expensive than my setup as the 5kw inverter will need g99 approval
£6885+£1450 = £8335
+£200 G99 fee
+extra £300 scaffolding (mine was £500)
should put it at a hair under £9k...
